Materials
- An octagonal shisima board with a centre point
- 3 large counters in each of two colours
How to play
- Join the eight vertices of an octagon around its edge. Add four straight lines between opposite vertices, crossing at a central playing point. There are nine points altogether.
- As shown, place your three counters on three consecutive outer points. Put the opponent’s three on the opposite three consecutive points. Leave two outer points and the centre empty.
- Choose who starts. Alternate moving one counter along a line to an adjacent empty point. No jumping, stacking or capturing.
- Win by aligning your three counters on a straight line through the centre. The same position with the same player to move three times is a draw. Change who starts.
Ways to adapt
Younger primary: mark and check each winning three-point line through the centre with colour.
